ITER is the only database that presents risk data in a tabular format for easy comparison, along with a synopsis explaining differences in data and a link to each organization for more information. Search Original ITER Search ITER on TOXNET ITER is currently available at its "Original ITER" location ( and is also available as part of the TOXNET compilation of databases ( The two locations contain the same information, however, the TOXNET display allows for additional search functions (click here to read a published manuscript describing how to use ITER on TOXNET). Edits to ITER are still made to the "Original ITER" location, which is uploaded to the TOXNET version of ITER on a weekly basis. The Risk Information Exchange (RiskIE) is a companion database to ITER.

Download the Chemical Reactivity Worksheet for Windows, Mac, or iPad. Reactivity is the tendency of substances to undergo chemical change, which can result in hazards—such as heat generation or toxic gas byproducts. The CRW predicts possible hazards from mixing chemicals and is designed to be used by emergency responders and planners, as well as the chemical industry, to help prevent dangerous chemical incidents.

The chemical datasheets in the CRW database contain information about the intrinsic hazards of each chemical and about whether a chemical reacts with air, water, or other materials. It also includes case histories on specific chemical incidents, with references. The Compatibility Chart shows the predicted hazards of mixing the chemicals in a mixture in an easy-to-use graphical interface.
